Image amplification in a self-imaging degenerate optical cavity [PDF]
Phys. Rev. A 101, 013824 (2020), 2019 Image-amplifying optical cavities offer an intriguing platform for nonlinear optical processing of two-dimensional signals, with potential applications in optical information processing and optically implemented artificial neural networks. Here, we analyze the performance of a self-imaging degenerate cavity via numerical simulations and show the ...

Optical Imaging of Pancreatic Innervation [PDF]
Frontiers in Endocrinology, 2021 At the time of Ivan Pavlov, pancreatic innervation was studied by looking at pancreas secretions in response to electrical stimulation of nerves. Nowadays we have ways to visualize neuronal activity in real time thanks to advances in fluorescent reporters and imaging techniques.

Can a conventional optical camera realize turbulence-free imaging? [PDF]
arXiv, 2021 Atmospheric turbulence is a serious problem for traditional optical imaging, especially for satellite and aircraft-to-ground imaging. Here, we report a novel and practical phenomenon in which turbulence-free images can be reconstructed on a conventional optical camera based on the accumulation of sunlight intensity and photon number fluctuation ...
